BACKGROUND

A service provider may operate a multi-tenant system to provide cloud-based processing, data storage and business-oriented applications to multiple tenants. In many circumstances, the tenants rely on the multi-tenant system to offer services, e.g., subscription billing services, to customers of tenant systems provided by the tenants.

One approach to monitoring performance conditions of the multi-tenant system is to manually check components of the system periodically. However, manual checking components scales poorly and fails to evaluate overall system health.

SUMMARY

DETAILED DESCRIPTION

FIG. 1 is a block diagram illustrating a network system 100 for testing the performance conditions of a multi-tenant system 108, in accordance with some embodiments of the present invention. The network system 100 includes client devices 102 coupled via a network (e.g., a set of one or more public and/or private, wired and/or wireless networks) to the multi-tenant system 108. Each of the client devices 102 includes a client system 104 that provides access to the shared services hosted by the multi-tenant system 108. The network system 100 further includes a development system 110 coupled to the network 106 for generating pre-production code 114 that becomes, updates and/or configures the multi-tenant system 108. The multi-tenant system 108 includes live (hot or online) components including a set of user interfaces 118, a set of server devices 120 and a set of data storage devices 122 that cooperate to host the services to the tenants. The network system 100 further includes a synthetic client system 112 that includes a testing system 116 configured to regularly test the performance conditions of the multi-tenant system 108.

Each client device 102 may include a desktop, laptop, notebook, tablet, personal digital assistant, smart phone, or other consumer electronic devices incorporating one or more computer components. The client system 104 on each client device 102 may include hardware, software and/or firmware for communicating with the multi-tenant system 108 and accessing the services hosted thereby. Examples of the client systems 104 may include web browsers, client engines, drivers, user interface components, proprietary interfaces, etc.

The development system 110 may include one or more server devices, application software and/or performance testing systems (e.g., Jenkins) capable of supporting generation of the code for the multi-tenant system 108. The development system 110 may support continuous integration and/or other code generation techniques.

The multi-tenant system 108 includes hardware, software and/or firmware to host the shared services for a plurality of tenants. Each tenant may include a group of one or more users, e.g., individuals, business entities, customers of the business entities, systems, etc., who share access to the hosted services. In one embodiment, the tenant includes the group of users of a service company such as AT&T, Netflix, etc. It will be appreciated that, typically, the typical multi-tenant system 108 offers multi-user access to shared applications on shared devices and offers each the same quality of service. That is, the multi-tenant system 108 does not use virtualization or instantiation processes, and does not vary quality of service among different tenants. In some embodiments, a multi-tenant system 108 integrates several business computing systems into a common system with a view toward streamlining business processes and increasing efficiencies on a business-wide level.

In some embodiments, the multi-tenant system 108 includes a user interface tier of multiple user interfaces 118, a server tier of multiple server devices 120, and a data storage tier of multiple data storage devices 122. In some embodiments, the user interfaces 118 include graphical user interfaces and/or web-based interfaces to enable tenants to access the shared services hosted by the multi-tenant system 108. The user interfaces 118 may support load balancing when multiple tenants (and/or multiple customers of the tenants) try to access the multi-tenant system 108 concurrently. The user interfaces 118 may additionally or alternatively include an operator interface for use by a systems operator to configure or otherwise manage the multi-tenant system 108. In some embodiments, each tenant may be associated with a subset of the total user interfaces 118 for load balancing.

In some embodiments, the server devices 120 include hardware, software and/or firmware to host the shared services for tenants. The hosted services may include tenant-specific business services or functions, including enterprise resource planning (ERP), customer relationship management (CRM), eCommerce, Human Resources (HR) management, payroll, financials, accounting, calendaring, order processing, subscription billing, inventory management, supply chain management (SCM), collaboration, sales force automation (SFA), marketing automation, contact list management, call-center support, web-based customer support, partner and vendor management systems, product lifecycle management (PLM), financial, reporting and analysis, etc. Similar to the user interfaces 118, in some embodiments, the server devices 120 may support load balancing when multiple tenants (and/or multiple customers of tenants) try to access the multi-tenant system 108 concurrently. Further, in some embodiments, each tenant may be associated with a subset of the total server devices 120 for load balancing.

In some embodiments, tenant data for each tenant may be stored in a logical store within a predetermined set of one or more data storage devices 122. In some embodiments, each tenant uses a logical store that is not assigned to any predetermined data storage devices 122. Each logical store may contain tenant data that is used, generated and/or stored as part of providing tenant-specific business services or functions. Each data storage device 122 may be implemented using any suitable data storage technology, including structured query language (SQL) based relational database management systems (RDBMS).

The testing system 116 may include hardware, software and/or firmware for testing performance conditions of the multi-tenant system 108. Testing of performance conditions may include evaluation of the health of each shared service provided through different combinations of user interfaces 118, server devices 120 and data storage devices 122. Testing of the health of each shared service may ensure that each shared service and/or system component (e.g., user interface 118, server device 120, data storage device 122, processor, memory, etc.) is available through each different path and meets certain performance conditions. In some embodiments, the testing system 116 is configured to select one of a set of credentials for logging into the multi-tenant system 108, to generate synthetic transactions in the multi-tenant system 108 for that selected one of the set of credentials, and to obtain and evaluate test results based on each synthetic transaction and/or combination of synthetic transactions. The testing system 116 may repeat the test for each of the set of credentials, such that each of the set of credentials test a different logical data store of all logical stores in the multi-tenant system 108. Evaluation of the test results may look to evaluate test result accuracy, lag times, resource use, errors noted, communication efficiency between components, etc. The testing system 116 may generate reports, alert response teams to problems, etc. In some embodiments, the testing system 116 may use actual tenant credentials to test actual tenant performance conditions for a synthetic transaction. When using actual tenant credentials, the testing system 116 may perform a clean-up to remove any history of the synthetic transaction.

In some embodiments, the testing system 116 may utilize portions of a pre-production testing system, e.g., the testing scripts defined during pre-production testing, for use in performing the live testing of the performance conditions of the multi-tenant system 108. In some embodiments, a third-party testing system (e.g., Jenkins) can be redirected from the pre-production code 114 in the deployment system 110 towards the production code in the multi-tenant system 108. In some embodiments, a third-party reporting system may be used to compile, process and generate reports from the tests results.

In some embodiments, the testing system 116 may use a keyword-driven automation framework, similar to the Unified Functional Testing (UFT), formerly known as QuickTest Professional (QTP), system provided by Hewlett-Packard®, that allows testers to develop test cases using a spreadsheet and a list of keywords. When a test is executed, the testing system 116 may process the spreadsheet and calls functions associated with keywords in the spreadsheet. The keyword functions perform specific actions against the multi-tenant system 108. The testing system 116 interprets each keyword and executes a set of statements in the multi-tenant system 108. In this manner, testing may be automated using application-specific keywords.

FIG. 2 is a block diagram illustrating details of the testing system 116, in accordance with some embodiments of the present invention. The testing system 116 includes an automated test driver 208 that is configured to receive start commands from a scheduler 206, to receive input data and at least one of a set of test scripts from an input data and test script store 202, and to generate and issues test commands to a controller 204 that provides synthetic transaction inputs to the multi-tenant system 108. The automated test driver 208 is further configured to receive test results from the multi-tenant system 108, to evaluate the test results, to generate logs, reports and data that are stored in a test results store 210, and to generate any necessary alerts 212.

The input data and test script store 202 stores input data and sets of one or more test scripts for performing a variety of synthetic transactions in the multi-tenant system 108. The input data may include access credentials, e.g., for a synthetic tenant of a set of synthetic tenants, and transaction data for one or more synthetic transactions. Each synthetic tenant of the set of synthetic tenants may include a unique synthetic user that accesses the hosted services to a different logical store. In some embodiments, the transaction data may be configured to be unique across all synthetic transactions (or unique across all synthetic transactions within a thread of synthetic transactions for each synthetic tenant) so that each synthetic transaction can be independently reviewed and evaluated. In some embodiments, the transaction data may be rendered unique using calendar/clock information. In some embodiments, each test script may be configured to support a synthetic transaction of a particular type and/or may be configured to test a particular logical store of the set of logical stores on the data storage devices 122. The input data and test script store 202 may store test scripts to generate synthetic transactions across all types of transactions available within the hosted services. In other words, a test script can be configured to evaluate the login process, to perform a particular synthetic transaction of a particular type (e.g., add/cancel/modify a billing entry, add/cancel/modify a contact, etc.), to evaluate a particular type of report (e.g., generate a list of all delinquent customer accounts, profit loss summary, etc.), to edit (e.g., add, delete, modify, etc.) particular tenant data, etc. In some embodiments, the test scripts may be configured from a default test script, e.g., by using the test data (such as the credential information) to identify the feature/function/destination/component being tested. In some embodiments, the test scripts and input data may be generated or reconfigured from test scripts and input data generated during pre-production for end-to-end testing of the performance conditions of the pre-production code 114 of the multi-tenant system 108.

The scheduler 206 may be configured to initiate synthetic transactions on a regular basis, for each tenant, for each path through the system, for each hosted service, for each logical data store, and/or the like. In some embodiments, the scheduler 206 initiates a synthetic transaction by generating and transmitting to the automated test driver 208 a start command to initiate performance of each synthetic transaction. The scheduler 506 may be configured to initiate a synthetic transaction periodically (e.g., every minute, every five minutes, once per day, once per week, etc.), at specific times of the day (e.g., at noon and 6 PM PT), upon the occurence of certain conditions (e.g., previously witnessed number of errors, when the processor reaches 80% use, after a tenant complaint, etc.). The scheduler 206 may initiate each synthetic transaction on a timing schedule based on predetermined conditions/preferences (e.g., every thirty minutes during certain times of the day, more often during other times or when errors are noted, etc.).

The scheduler 206 may initiate different threads (chains) of synthetic transactions on a regular basis, each thread being associated with a different path and/or logical data store (e.g., tenant type) though the multi-tenant system 108. A tenant type may be defined based the particular logical data store and/or data storage device(s) 122 in which the tenant data is stored. For example, the scheduler 206 may initiate a first thread of synthetic transactions at a first frequency/timing for a first synthetic tenant whose tenant data is stored in a first logical data store and/or a first data storage device 122, a second thread of synthetic transactions at a second frequency/timing for a second synthetic tenant whose tenant data is stored in a second logical data store and/or second data storage device 122, etc. The synthetic transactions of each thread may be initiated with the same timing and/or different timing as other threads. The synthetic transactions of each thread of synthetic transactions may be initiated with timing dependent on predetermined criteria/preferences (e.g., previously witnessed number of errors, processor use, tenant complaints, etc.). The scheduler 206 may initiate several synthetic transactions across different paths and/or to different logical data stores or different data storage devices 122 in parallel. Additional details regarding initiation of synthetic transactions are provided below with reference to FIG. 3.

The automated test driver 208 includes hardware, software and/or firmware configured to receive the start command from the scheduler 206 for a synthetic transaction, to receive input data and a test script from the input data and test script store 202 for the synthetic transaction, and to generate and issue test commands to the controller 204 for causing the multi-tenant system 108 to perform the synthetic transaction. The automated test driver 208 further includes hardware, software and/or firmware to receive test results from the multi-tenant system 108, to evaluate the test results, to generate and store logs, reports and data in the test results store 210, and to generate any necessary alerts 212. Further details are provided below.

The controller 204 includes hardware, software and/or firmware configured to receive test commands from the automated test driver 208 and to generate and transmit synthetic transaction inputs to the multi-tenant system 108 for causing the multi-tenant system to perform the synthetic transaction. The synthetic transaction inputs include control information, which the multi-tenant system 108 uses to perform the synthetic transaction requested, e.g., login, execution of the synthetic transaction, generation of the report, etc. In some embodiments, the controller 204 includes a browser controller, which controls a web browser that communicates with the web server on the multi-tenant system 108. In some embodiments, the controller 204 includes an application programming interface (API). In some embodiments, the controller 204 includes a client engine controller. In some embodiments, the controller 204 includes a user interface controller. Other alternative controllers are possible. Like other components on the testing system 116 (e.g., the input data and test script store 202, the scheduler 206, the test result store 210, etc.), the controller 204 may be on the multi-tenant system 108, on the synthetic client system 112, or on systems remote from the multi-tenant system 108 and from the testing system 116.

In some embodiments, the automated test driver 208 is configured to evaluate the test results received from the multi-tenant system 108 in response to the synthetic transaction inputs against threshold/expected performance data. Example performance data may include time-based information (e.g., a threshold time period for a login to occur, a threshold time period for the test results to be received), accuracy-based information (e.g., the expected test results in response to the synthetic transaction), component-based information (e.g., threshold capacity for processor utilization, correct handoff information for each component to send to a subsequent component), etc. The automated test driver 208 may be configured to generate an alert, such as an email, text, telephone call or other communication when a trigger condition is met, e.g., when any threshold condition is not met, when a predetermined threshold condition is not met, and/or when several threshold conditions are not met (e.g., two or more sequential threshold conditions are not met, two or more threshold conditions are not met during peak use, etc.). The automated test driver 208 may be configured to transmit the test results and the test reports to the test result store 210 for storage.

An example set of the test results for a single synthetic transaction is provided below:

FIG. 3 is a block diagram illustrating a multi-path/destination testing system 300, in accordance with some embodiments of the invention. The multi-path/destination testing system 300 includes multiple test scripts 302 being executed in parallel to test performance conditions of the multiple paths/destinations 306 of the multi-tenant system 108. As illustrated, the test script 1 may be executed to test the performance condition of path/destination 1 of the multiple paths/destinations 306 of the multi-tenant system 108. The test script 2 may be executed to test the performance condition of path/destination 2 of the multiple paths/destinations 306 of the multi-tenant system 108. The test script 3 may be executed to test the performance condition of path/destination 3 of the multiple paths/destinations 306 of the multi-tenant system 108. The test script 4 may be executed to test the performance condition of path/destination 4 of the multiple paths/destinations 306 of the multi-tenant system 108. The test script N may be executed to test the performance condition of path/destination N of the multiple paths/destinations 306 of the multi-tenant system 108. The arrow from a test script 302 to the multi-tenant system 108 reflects synthetic transaction inputs. The arrow from the multi-tenant system 108 to a test script 302 reflects test results in response to the synthetic transaction inputs.

In some embodiments, the path/destination 1 may include a generally random communication path through one of the several available user interfaces 118 and through one of the several available server devices 120 to a predetermined logical store in one or more of the data storage devices 122. It will be appreciated that each time test script 1 is executed, the same or an alternative of the multiple available paths to the predetermined logical store may be taken. That is, the path/destination 1 may include a communication path through the same or a different one of the several available user interfaces 118 and through the same or a different one of several available server devices 120 as the previous test instance to the predetermined logical store. The test script 1 can be executed regularly so that, statistically, the test script 1 will test all of the different communication paths of user interface 118 and server devices 120 to the predetermined logical store, and so that during runtime each path is statistically ensured to be evaluated a sufficient number of times in a given time period.

Test scripts 2-N may operate similarly to test script 1. Further, two or more of test scripts 1-N may be executed in parallel to test the respective paths/destinations 1-N of available user interfaces 118 and server devices 120 to the respectively predetermined logical stores. It will be appreciated that execution of each test script 1-N may be initiated at different times, with different timing (e.g., frequency), in response to different triggers, with different timing based on the different triggers, etc. Notably, each test script 1-N may be executed based on a frequency associated with the number of available communication paths to each of the predetermined logical stores.

In some embodiments, each of the test scripts 1-N may be dedicated to a particular communication path including a particular user interface 118, a particular server device 120 and/or a particular logical store, to ensure that each communication path is evaluated (and to remove the element of randomness).

In some embodiments, each test script will include a several tests for several synthetic transactions to sufficiently test end-to-end the services offered by the multi-tenant system 108. In some embodiments, there may be multiple test scripts 1 (e.g., 1 a-1 n) associated with a communication path/destination 1 through the multi-tenant system 108, such that each test script 1 may test different performance conditions of a different feature, function or component of the communication path (whether applying a dedicated embodiment or a random embodiment described above).

FIG. 4 is a block diagram illustrating details of the automated test driver 208, in accordance with some embodiments of the invention. The automated test driver 208 includes a scheduler interface 402, an input data and test script loader 404, a test command generator 406, a test result receiver 408, a test result evaluation engine 410, a test result store interface 412, and an alert generator 414.

The scheduler interface 402 includes hardware, software and/or firmware configured to communicate with the scheduler 206 to initiate a synthetic transaction. The scheduler interface 402 may receive identification of input data, a test script, a path/destination 1-N, and/or a synthetic transaction. In other embodiments, the test command generator 406 may make the selections of input data, test script, path/destination 1-N and/or synthetic transaction.

The input data and test script loader 404 includes hardware, software and/or firmware configured to communicate with the input data and test script store 202 to obtain input data and a test script and to load the input data and test script for execution.

The test command generator 406 includes hardware, software and/or firmware configured to use the input data and test script to generate and communicate test commands to the controller 204, so that the controller can generate the synthetic transaction inputs to the multi-tenant system 108. The test command generator 406 may generate test commands to instruct the controller 204 to generate several different synthetic transactions through a path/destination 1-N in the multi-tenant system 108.

The test result receiver 408 includes hardware, software and/or firmware configured to receive test results from the multi-tenant system 108 in response to the synthetic transaction inputs. In some embodiments, the test result receiver 408 may communicate directly with the multi-tenant system 108. In some embodiments, the test result receiver 408 may communicate indirectly, e.g., through the controller 204 or through a different controller.

The test result evaluation engine 410 includes hardware, software and/or firmware configured to evaluate the test results. Evaluation of the test results may include comparison against threshold/expected performance data. Evaluation of the test results may include comparing actual time measurements against threshold time values (e.g., did login occur within a threshold time period, were the test results received within a threshold time period). Evaluation of the test results may include comparing actual test result values against expected test result values (e.g., were the test results accurate). Evaluation of the test results may include comparing actual component metrics against threshold component metrics (e.g., was the processor utilization below threshold capacity, was memory utilization below threshold capacity). Evaluation of the test results may include comparing the information each component passes to information each component is expected to pass.

The test result store interface 412 includes hardware, software and/or firmware configured to communicate with the test results store 210 to store the test results, logs, test reports, etc.

The alert generator 414 includes hardware, software and/or firmware configured to evaluate alert trigger conditions to determine whether to generate an alert, e.g., an email, text, telephone call or other communication. The alert generator 414 may determine when an alert trigger condition is met. For example, an alert condition may occur when any threshold condition is not met. An alert condition may occur when a predetermined threshold condition is not met. An alert trigger condition may occur when several threshold conditions are not met, e.g., two or more sequential threshold conditions are not met, two or more threshold conditions are not met during peak use, etc. An alert trigger condition may occur when a particular path appears corrupted. An alert trigger condition may occur when a particular component appears to have failed or to not be operating at a threshold performance level. Other alert trigger conditions are possible.

FIG. 5 illustrates an example test result status interface 500, in accordance with some embodiments of the invention. As illustrated, the example test result status interface 500 includes test result indicators 502 for a plurality of paths (referred to as a production shard or “Prod Shard”) through the multi-tenant system 108. Each production shard is associated with a path identifier (1, 10, 11, 12 . . . 29, 3). Each test result indicator 502 indicates the amount of time that transpired since the last test event (e.g., a moment ago, 9 minutes ago, etc.). Each test result indicator 502 may be presented as a particular color based on the performance condition (status) reflected by the last test. For example, the test result flag 502 may be green to reflect the path as healthy, light green to reflect the path as in the process of being tested and thus far passing, yellow to reflect the path as having failed the last test and at risk (but not yet amounting to an alert trigger condition), light yellow to reflect the path as in the process of being tested and failing, red to reflect an alert trigger condition, light red to reflect the path as transitioning from healthy or at risk status to an alert trigger condition. Other color and/or visual aids may be used to reflect the different performance conditions of the different paths.

FIG. 6 is a flowchart illustrating a method 600 of testing a multi-tenant system, such as the multi-tenant system 108, in accordance with some embodiments of the invention. Method 600 begins with the scheduler 206 in step 602 determining whether to initiate a synthetic transaction in the multi-tenant system 108. In some embodiments, the scheduler 206 in step 602 determines whether to initiate a synthetic transaction of a particular path/destination of the multi-tenant system 108. The input data and test script loader of the automated test driver 208 in step 604 loads the test script and in step 606 loads the input data for the particular synthetic transaction. In step 608, the test command generator 406 of the automated test driver 208 generates and provides test commands to the controller 204, the controller 204 generates and provides synthetic transaction inputs to the multi-tenant system 108, and the multi-tenant system 108 performs the synthetic transaction based on the synthetic transaction inputs. In step 610, the test result receiver 408 receives the test results from the multi-tenant system 108, directly or indirectly.

In step 612, the test result evaluation engine 410 evaluates the test results to determine whether an alert condition has been triggered. If not, then in step 616 the test result store interface 412 stores the test results and/or evaluation reports into the test result store 210. If an alert condition has been triggered, then in step 614 the alert generator 414 generates an alert, and method 600 proceeds to step 616 to log the results and/or evaluation reports. After logging the test results and/or evaluation reports in the test results store 210, method 600 then returns to step 602 to determine whether to initiate another test. In some embodiments, multiple parallel methods 600 operate to test multiple paths/destinations of the multi-tenant system 108.

FIG. 7 is a block diagram of an exemplary digital device 700. Any of the client 102, development system 110, synthetic client 112 and/or multi-tenant system 108 may include and/or be implemented on one or more digital devices 700. The digital device 700 comprises a processor 702, a memory system 704, a storage system 706, a communication network interface 708, an I/O interface 710, and a display interface 712 communicatively coupled to a bus 714. The processor 702 is configured to execute executable instructions (e.g., programs). In some embodiments, the processor 702 comprises circuitry or any processor capable of processing the executable instructions.

The memory system 704 is any memory configured to store data. Some examples of the memory system 704 are storage devices, such as RAM or ROM. The memory system 704 can comprise the RAM cache. In various embodiments, data is stored within the memory system 704. The data within the memory system 704 may be cleared or ultimately transferred to the storage system 706.

The storage system 706 is any storage configured to retrieve and store data. Some examples of the storage system 706 are flash drives, hard drives, optical drives, and/or magnetic tape. In some embodiments, the digital device 700 includes a memory system 704 in the form of RAM and a storage system 706 in the form of flash data. Both the memory system 704 and the storage system 706 comprise computer readable media which may store instructions or programs that are executable by a computer processor including the processor 702. The storage system 706 may comprise non-transitory media. One skilled in the art will recognize that, although the storage system 706 and memory system 704 are illustrated as different units, the storage system 706 and memory 704 can be parts of the same unit, distributed units, virtual memory, etc.

The communications network interface (com. network interface) 708 can be coupled to a network via the link 716. The communication network interface 708 may support communication over an Ethernet connection, a serial connection, a parallel connection, or an ATA connection, for example. The communication network interface 708 may also support wireless communication (e.g., 802.11 a/b/g/n, WiMax). It will be apparent to those skilled in the art that the communication network interface 708 can support many wired and wireless standards.

The input/output (I/O) interface 710 is any device that receives input from the user and/or outputs data. The display interface 712 is any device that is configured to output graphics and data to a display. In one example, the display interface 712 is a graphics adapter.

It will be appreciated by those skilled in the art that the hardware elements of the digital device 700 are not limited to those depicted in FIG. 7. A digital device 700 may comprise more or less hardware elements than those depicted. Further, hardware elements may share functionality and still be within various embodiments described herein. In one example, encoding and/or decoding may be performed by the processor 702 and/or a co-processor located on a GPU (e.g., an Nvidia® co-processor).

One skilled in the art will recognize that the digital device 700 may also include additional information, such as network connections, additional memory, additional processors, LANs, input/output lines for transferring information across a hardware channel, access to the Internet or an intranet, etc. One skilled in the art will also recognize that the programs and data may be received by and stored in the system in alternative ways. For example, a computer-readable storage medium (CRSM) reader such as a magnetic disk drive, hard disk drive, Flash drive, CPU, etc. may be coupled to the bus 714 for reading a computer-readable storage medium (CRSM) such as a magnetic disk, a hard disk, a magneto-optical disk, RAM, etc. Accordingly, the digital device 700 may receive programs and/or data via the CRSM reader. Further, it will be appreciated that the term “memory” herein is intended to cover all data storage media whether permanent or temporary.
